LEO: July 31-Aug. 6

LEO (July 23-Aug. 22): Sergei Diaghilev, a Russian ballet impresario, founded Ballets Russes, one of the 20th century's great ballet companies. When he met French playwright Jean Cocteau, he dared him to write a piece for a future Ballets Russes production. "Astonish me!" he said. It took seven years, but Cocteau met the challenge. He created Parade, a ballet that featured music by Eric Satie and sets by Pablo Picasso. Let's pretend I'm Diaghilev and you're Cocteau, and I've just demanded "Astonish me!" What surprising beauty do you create? What marvels do you unleash?
